+// DISCLAIMER:
+// This software is furnished "as is", without technical support, and with no
+// warranty, express or implied, as to its usefulness for any purpose.
+//
+// BACKGROUND:
+// When I first received an ultrasonic sensor I was not happy with how poorly
+// it worked. Quickly I realized the problem wasn't the sensor, it was the
+// available ping and ultrasonic libraries causing the problem. The NewPing
+// library totally fixes these problems, adds many new features, and breaths
+// new life into these very affordable distance sensors.
+//
+// FEATURES:
+// * Works with many different ultrasonic sensors: SR04, SRF05, SRF06, DYP-ME007, URM37 & Parallax PING))).
+// * Compatible with the entire Arduino line-up (and clones), Teensy family (including $19 96Mhz 32 bit Teensy 3.2) and non-AVR microcontrollers.
+// * Interface with all but the SRF06 sensor using only one Arduino pin.
+// * Doesn't lag for a full second if no ping/echo is received.
+// * Ping sensors consistently and reliably at up to 30 times per second.
+// * Timer interrupt method for event-driven sketches.
+// * Built-in digital filter method ping_median() for easy error correction.
+// * Uses port registers for a faster pin interface and smaller code size.
+// * Allows you to set a maximum distance where pings beyond that distance are read as no ping "clear".
+// * Ease of using multiple sensors (example sketch with 15 sensors).
+// * More accurate distance calculation (cm, inches & uS).
+// * Doesn't use pulseIn, which is slow and gives incorrect results with some ultrasonic sensor models.
+// * Actively developed with features being added and bugs/issues addressed.
+//
+// CONSTRUCTOR:
+//   NewPing sonar(trigger_pin, echo_pin [, max_cm_distance])
+//     trigger_pin & echo_pin - Arduino pins connected to sensor trigger and echo.
+//       NOTE: To use the same Arduino pin for trigger and echo, specify the same pin for both values.
+//     max_cm_distance - [Optional] Maximum distance you wish to sense. Default=500cm.
+//
+// METHODS:
+//   sonar.ping([max_cm_distance]) - Send a ping and get the echo time (in microseconds) as a result. [max_cm_distance] allows you to optionally set a new max distance.
+//   sonar.ping_in([max_cm_distance]) - Send a ping and get the distance in whole inches. [max_cm_distance] allows you to optionally set a new max distance.
+//   sonar.ping_cm([max_cm_distance]) - Send a ping and get the distance in whole centimeters. [max_cm_distance] allows you to optionally set a new max distance.
+//   sonar.ping_median(iterations [, max_cm_distance]) - Do multiple pings (default=5), discard out of range pings and return median in microseconds. [max_cm_distance] allows you to optionally set a new max distance.
+//   NewPing::convert_in(echoTime) - Convert echoTime from microseconds to inches (rounds to nearest inch).
+//   NewPing::convert_cm(echoTime) - Convert echoTime from microseconds to centimeters (rounds to nearest cm).
+//   sonar.ping_timer(function [, max_cm_distance]) - Send a ping and call function to test if ping is complete. [max_cm_distance] allows you to optionally set a new max distance.
+//   sonar.check_timer() - Check if ping has returned within the set distance limit.
+//   NewPing::timer_us(frequency, function) - Call function every frequency microseconds.
+//   NewPing::timer_ms(frequency, function) - Call function every frequency milliseconds.
+//   NewPing::timer_stop() - Stop the timer.
+//
+// HISTORY:
+// 07/30/2016 v1.8 - Added support for non-AVR microcontrollers. For non-AVR
+//   microcontrollers, advanced ping_timer() timer methods are disabled due to
+//   inconsistencies or no support at all between platforms. However, standard
+//   ping methods are all supported. Added new optional variable to ping(),
+//   ping_in(), ping_cm(), ping_median(), and ping_timer() methods which allows
+//   you to set a new maximum distance for each ping. Added support for the
+//   ATmega16, ATmega32 and ATmega8535 microcontrollers. Changed convert_cm()
+//   and convert_in() methods to static members. You can now call them without
+//   an object. For example: cm = NewPing::convert_cm(distance);
+//
+// 09/29/2015 v1.7 - Removed support for the Arduino Due and Zero because
+//   they're both 3.3 volt boards and are not 5 volt tolerant while the HC-SR04
+//   is a 5 volt sensor.  Also, the Due and Zero don't support pin manipulation
+//   compatibility via port registers which can be done (see the Teensy 3.2).
+//
+// 06/17/2014 v1.6 - Corrected delay between pings when using ping_median()
+//   method. Added support for the URM37 sensor (must change URM37_ENABLED from
+//   false to true). Added support for Arduino microcontrollers like the $20
+//   32 bit ARM Cortex-M4 based Teensy 3.2. Added automatic support for the
+//   Atmel ATtiny family of microcontrollers. Added timer support for the
+//   ATmega8 microcontroller. Rounding disabled by default, reduces compiled
+//   code size (can be turned on with ROUNDING_ENABLED switch). Added
+//   TIMER_ENABLED switch to get around compile-time "__vector_7" errors when
+//   using the Tone library, or you can use the toneAC, NewTone or
+//   TimerFreeTone libraries: https://bitbucket.org/teckel12/arduino-toneac/
+//   Other speed and compiled size optimizations.
+//
+// 08/15/2012 v1.5 - Added ping_median() method which does a user specified
+//   number of pings (default=5) and returns the median ping in microseconds
+//   (out of range pings ignored). This is a very effective digital filter.
+//   Optimized for smaller compiled size (even smaller than sketches that
+//   don't use a library).
+//
+// 07/14/2012 v1.4 - Added support for the Parallax PING)))� sensor. Interface
+//   with all but the SRF06 sensor using only one Arduino pin. You can also
+//   interface with the SRF06 using one pin if you install a 0.1uf capacitor
+//   on the trigger and echo pins of the sensor then tie the trigger pin to
+//   the Arduino pin (doesn't work with Teensy). To use the same Arduino pin
+//   for trigger and echo, specify the same pin for both values. Various bug
+//   fixes.
+//
+// 06/08/2012 v1.3 - Big feature addition, event-driven ping! Uses Timer2
+//   interrupt, so be mindful of PWM or timing conflicts messing with Timer2
+//   may cause (namely PWM on pins 3 & 11 on Arduino, PWM on pins 9 and 10 on
+//   Mega, and Tone library). Simple to use timer interrupt functions you can
+//   use in your sketches totally unrelated to ultrasonic sensors (don't use if
+//   you're also using NewPing's ping_timer because both use Timer2 interrupts).
+//   Loop counting ping method deleted in favor of timing ping method after
+//   inconsistent results kept surfacing with the loop timing ping method.
+//   Conversion to cm and inches now rounds to the nearest cm or inch. Code
+//   optimized to save program space and fixed a couple minor bugs here and
+//   there. Many new comments added as well as line spacing to group code
+//   sections for better source readability.
+//
+// 05/25/2012 v1.2 - Lots of code clean-up thanks to Arduino Forum members.
+//   Rebuilt the ping timing code from scratch, ditched the pulseIn code as it
+//   doesn't give correct results (at least with ping sensors). The NewPing
+//   library is now VERY accurate and the code was simplified as a bonus.
+//   Smaller and faster code as well. Fixed some issues with very close ping
+//   results when converting to inches. All functions now return 0 only when
+//   there's no ping echo (out of range) and a positive value for a successful
+//   ping. This can effectively be used to detect if something is out of range
+//   or in-range and at what distance. Now compatible with Arduino 0023.
+//
+// 05/16/2012 v1.1 - Changed all I/O functions to use low-level port registers
+//   for ultra-fast and lean code (saves from 174 to 394 bytes). Tested on both
+//   the Arduino Uno and Teensy 2.0 but should work on all Arduino-based
+//   platforms because it calls standard functions to retrieve port registers
+//   and bit masks. Also made a couple minor fixes to defines.
+//
+// 05/15/2012 v1.0 - Initial release.

+// ping time. The advantage of using this method over the standard ping method is that it permits a more
+// event-driven sketch which allows you to appear to do two things at once. An example would be to ping
+// an ultrasonic sensor for a possible collision while at the same time navigating. This allows a
+// properly developed sketch to multitask. Be aware that because the ping_timer method uses Timer2,
+// other features or libraries that also use Timer2 would be effected. For example, the PWM function on
+// pins 3 & 11 on Arduino Uno (pins 9 and 11 on Arduino Mega) and the Tone library. Note, only the PWM
+// functionality of the pins is lost (as they use Timer2 to do PWM), the pins are still available to use.
